I'd suggest that it might be better to create a separate RailWiki, as the MediaWiki software is open source so anyone can use it to host their own Wiki project. The level of detail that you're suggesting is better suited to a specialist railway encyclopaedia, rather than a general one.
Hum.. given what some of the posters on this forum have to say the mind rather boggles at what the AGA entry would say should your suggestion be implemented
